Hydraulic versus Pneumatic Door Closers

I have had a lot of customers ask the difference between a hydraulic (liquid-operation) and pneumatic (gas-operation) door closer, and I've never had a straight answer for them.  Google couldn't even tell me...  After discussing it with Dean, we came to the conclusion that the pneumatic closer is better for all weather conditions (hot/cold weather can change the viscosity of the liquid in a hydraulic system, making it close at different speeds at different temperatures).  The hydraulic closer provides a smoother, 'no bounce' action, but is affected by temperature.  Both styles are adjustable.

    Interesting. I also read:

    If your storm door is closing too fast or not shutting all the way, consider replacing its pneumatic door closer with a new hydraulic door closer.

    Hydraulic closers allow storm doors to close smoothly, eliminating the quick start and slow finish of traditional closers. Hydraulic closers also do a better job of pulling the door closed and keeping it shut.
